How to find which version of TensorFlow is installed in my system?

Question

I need to find which version of TensorFlow I have installed. I'm using Ubuntu 16.04 Long Term Support.

Answer 1

This depends on how you installed TensorFlow. I am going to use the same headings used by TensorFlow's installation instructions to structure this answer.

---

Pip installation

Run:

python -c 'import tensorflow as tf; print(tf.__version__)'  # for Python 2 python3 -c 'import tensorflow as tf; print(tf.__version__)'  # for Python 3 

Note that python is symlinked to /usr/bin/python3 in some Linux distributions, so use python instead of python3 in these cases.

pip list | grep tensorflow for Python 2 or pip3 list | grep tensorflow for Python 3 will also show the version of Tensorflow installed.

Virtualenv installation

Run:

python -c 'import tensorflow as tf; print(tf.__version__)'  # for both Python 2 and Python 3 

pip list | grep tensorflow will also show the version of Tensorflow installed.

For example, I have installed TensorFlow 0.9.0 in a virtualenv for Python 3. So, I get:

$ python -c 'import tensorflow as tf; print(tf.__version__)' 0.9.0  $ pip list | grep tensorflow tensorflow (0.9.0) 

Answer 2

Almost every normal package in python assigns the variable .__version__ to the current version. So if you want to find the version of some package you can do the following

import a a.__version__ 

For tensorflow it will be

import tensorflow as tf tf.version.VERSION 

For old versions of tensorflow (below 0.10), use tf.__version__
